This is an ashamingly simple object, but it has proved indespensable in my game. It's a pile of sand that functions as a pegbox and it's super useful for playgrounds, beaches, junkyards, farms, poor families and many more. You can also CAST it into mud, pebbles, leaves and many more.

You can even place it in an "official" sandbox with "moveObjects on", so toddlers can finally join their older siblings on the playground. It won't keep children from playing in the sand, provided, there is still enough space in the sandbox.
